These worked examples illustrate the use of the BUGS language and sampler in a wide range of problems. They contain a number of useful ``tricks", but are certainly not exhaustive of the models that may be analysed.
We emphasise that all the results for these examples have been derived in the most naive way: in general a burn-in of 500 iterations and a single long run of 1000 iterations. This is not recommended as a general technique: no tests of convergence have been carried out, and traces of the estimates have not even been plotted. However, comparisons with published results have been made where possible. Times have been measured on a 60 MHz superSPARC: a 60 MHz Pentium PC appears to be about 4 times slower, and a 30 MHz superSPARC about 2 times slower.
Users are warned to be extremely careful about assuming convergence, especially when using complex models including errors in variables, crossed random effects and intrinsic priors in undirected models.
